The standard pre-amp system is limited by the nonlinearities in the fiber amplifier, hence a 1nJ output energy. We can, however, customise a system that reduces the peak power by stretching the pulse prior to the input, followed, if required by post-amplification compression. In this way, we can boost the output of the 1µm narrow bandwidth beam up to ~100nJ at reduced repetition rate of 1 MHz. Related: venteon
